Can a mini-motor set-up be zapped with poly neo magnets? If so, where can I send them? My motors seem to be flat - it's got speed, but no snap or torque.

As far as I understand they require a specific, very expensive solution to zap, even initially. I believe the Chinese manufacturers are some of the few that actually own them. When I emailed Proslot it was mentioned to use ceramic if I wanted to be able to rezap in the states. I believe if you can heat up the glue and remove them they can be replaced completely. Might be easier to just buy another newer setup, PS-9027 for proslot poly neo setups and then the PS-9003 for the ceramic setups. These are the newer open can design btw.


I recently spent a bit on a PSL9002-12CPRBB.. this motor is ceramic based and with copper hardware and ball bearings. It's pretty darn fast and screams almost like a group 27 (it's an X-12 arm). Sorry to deviate from your initial question but I recently went down a similar path.

You might call on Mid-America. They bought the Sonic zapper a few years ago and that machine is more than capable of recharging the neo, or any other, magnets used in slot cars. It had the capacity to magnetically saturate a 30 pound piece of alnico material. A set of magnets weighing grams isn't a problem.


Whether MA is zapping magnets as a service is unknown.


Poly magnets degrade easily with heat. Once they oxidize (this goes for CoSm magnets too) they lose their ability to be restored to original specs. The oxide reaches below the surface of the magnet and effectively reduces the volume of the magnet. The surface oxidation also interferes with the magnetic flux. Notice that when you buy commercial RE magnets they're nickel plated. This is for protection of the surface of the magnet from oxidation.
